Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for academic research. Nothing else comes close for systematic reviews.
